Last week Google hosted a Data Center Efficiency Summit, bringing together approximately 160 industry leaders to share insights and best practices. Since it was April Fool's Day, we threw in a few jokes to keep the atmosphere fun (oil-cooled data center, anyone?), but the topic is serious: How can the IT industry keep growing while also exercising good environmental stewardship?

We disclosed for the first time details about the design of our ultra-efficient data centers. We also provided a first-ever video tour of a Google container data center as well as a water treatment facility. We detailed how we measure data center efficiency and discussed how we reduced our facility energy use by up to 85%. The engineers who developed our efficient battery backup solution even brought an actual Google server to the event.

By the end of the day, we narrowed in on a recurring theme: Reducing resource use through efficiency efforts is not just good for the environment, it saves money too. And it is this economic advantage which makes efficient data centers not just green, but truly sustainable.
